According to the modification shown .in Fig. 3, I provide instead of the twin screws for controlling the wedges adjusting the brass segments, single screw bolts 70 engaging with theirthreaded part one of the two wedges, while the worm n is journalled 1n the other wedge. The worm wheel m meshing with said worm is secured to and near the end of the screw bolt is.

According to Fig. 3 the bush of the bearing is split into three segments instead of four, as shown in Fig. 1 and the slots are spaced 120'? apart. A further improvement shown in Figs. 3 and 4 are the wedges p inserted between the adjacent faces of the brass segments. 1' is a screw for securing the wedges ,p to the brass segments and which cooperate with said wedges to allow pivotal respective adjustment of said bushes. Said wedges, are for securing the brass segmentsin their relative concentric positions even-though the bearing is worn out to such a degree that the journal would not hold the brasses in their proper positions.

I have shown further strips 8 of elastic and oil proof material. such as felt, filling the-space between the adjacent brass segments and preventing the lubricant from flowing. I

It should be understood that I do not limit my invention to the construction shown as an example in the drawing for obviously the distance surfaces f may be of a greater or smaller breadth, and may be reduced to mere ribs or edges. Thevrnay be formed integralwith the front plates of the stator shell, or. may be inserted as separate hardened pieces, It may be further understood that the slots extending through the brasses to the journal need not be located between the brass segments, but may be formed within these segments at any accessible point thereof.

Although it is preferable to dispose the distance faces at equal distances from the journal. thev mav be located at different distances. This difference must, however,

taken into consideration when adjustments are made.
